Abstract

The invention discloses a craftwork fire-retardant coating. The craftwork fire-retardant coating is a porous fire-retardant resin prepared by melting diatomite in high-polymer resin. The craftwork fire-retardant coating is excellent in fire-retardant and thermal-insulating performance, and can self-quench within 1-2 seconds when isolated from a source of combustion; also, the craftwork fire-retardant coating is low in thermal conducting coefficient, high in hydrophobicity and convenient to apply, can be applied to countering hazardous fire and can form a protective layer on the surface of a wooden craftwork after retarding fire to block internal damage without affecting the service life of the wooden craftwork. The craftwork fire-retardant coating is an effective manner for improving the fire-retardant performance of the wooden craftwork, is simple in preparation, energy-efficient, environmentally friendly and high in use efficiency and has the advantages of being convenient to operate, safe, reliable, and long in durability and the like, thereby being very worthwhile popularization and application.

Description

technical field [0001] The invention belongs to the technical field of wooden crafts processing industry, and in particular relates to a flame-retardant coating for wooden crafts. Background technique [0002] Wood is the lignified tissue of plants capable of secondary growth, such as trees and shrubs. After the primary growth of these plants ends, the vascular cambium in the rhizome becomes active, developing bast outward and wood inward. Wood is the general term for plant tissues that develop inwardly from the vascular cambium, including xylem and parenchyma rays. Wood plays a great supporting role in human life. According to the different properties and characteristics of wood, people use them in different ways. Wooden handicrafts in the broad sense use various woods (including various bamboos) as the main raw materials, while wooden handicrafts in the narrow sense mainly use various woods as raw materials. Fine workmanship, simple design, different styles, natural co...
